Functions[edit] A function, which can also be referred to as subroutine, procedure, subprogram or even method, carries out tasks defined by a sequence of statements called a statement block that need only be written once and called by a program as many times as needed to carry out the same task.
To display the definition of a function several methods can be used: cat function:Add-Numbers or ${function:Add-Numbers} or (get-command Add-Numbers).definition. To list all functions in the current session: get-command-CommandType function. N.B in a block of code you need to define the function before you call it.
